They are compatible, and can share transducers over the Ethernet, but to share waypoints they need a NMEA 2000 network.

Hey guys. My dad has a lowrance lms-520c on his transom. And is looking to upgrade to a side imaging and move his current unit to the bow. We were wondering if they are compadible and will share GPS coords with the Ethernet cable. Looking at the hds7 or 8. Thanks guys
